Old Dutch

In linguistics, Old Dutch (Modern Dutch: Oudnederlands) or Old Low Franconian (Modern Dutch: Oudnederfrankisch) is the set of dialects that evolved from Frankish spoken in the Low Countries during the Early Middle Ages, from around the 6th to the 12th century. Old Dutch is mostly recorded on fragmentary relics, and words have been reconstructed from Middle Dutch and Old Dutch loanwords in French.

Old Dutch is regarded as the primary stage in the development of a separate Dutch language. It was spoken by the descendants of the Salian Franks who occupied what is now the southern Netherlands, northern Belgium, part of northern France, and parts of the Lower Rhine regions of Germany. It evolved into Middle Dutch around the 12th century. The inhabitants of northern Dutch provinces, including Groningen, Friesland, and the coast of North Holland, spoke Old Frisian, and some in the east (Achterhoek, Overijssel, and Drenthe) instead spoke Old Saxon.

Within the field of historical philology, the terminology for the oldest historical phase of the Dutch language traditionally includes both Old Dutch as well as Old Low Franconian. In English linguistic publications, Old Netherlandic is occasionally used in addition to the aforementioned terms.

Old Low Franconian, derives from the linguistic category first devised by the German linguist Wilhelm Braune (1850–1926), who used the term Franconian as a wastebasket taxon for the early West Germanic texts that he could not readily classify as belonging to either Saxon, Alemannic or Bavarian and assumed to derive from the language of the Franks. He subsequently further divided this new grouping into Low, Middle and High Franconian based on the absence or presence of the Second Germanic consonant shift. With the exception of Dutch, modern linguistic research has challenged the direct diachronical connection to Old Frankish for most of the varieties grouped under the broader "Franconian" category. Nevertheless, the traditional terminology of the West Germanic varieties along assumed Late Classical tribal lines, typical of 19th and early 20th century Germanic linguistics, remains common.

Within historical linguistics Old Low Franconian is synonymous with Old Dutch. Depending on the author, the temporal boundary between Old Dutch and Old Frankish is either defined by the onset of the Second Germanic consonant shift in Eastern Frankish, the assimilation of an unattested coastal dialect showing North Sea Germanic-features by West Frankish during the closing of the 9th century, or a combination of both. Some linguists use the terms Old Low Franconian or West Frankish to specifically refer to the (very sparsely attested) varieties of Old Dutch spoken prior its assimilation of the coastal dialect.

Old Dutch itself is further divided into Old West Dutch and Old East Dutch, with the descendants of Old West Dutch forming the dominant basis of the Middle Dutch literary language and Old East Dutch forming a noticeable substrate within the easternmost Dutch dialects, such as Limburgish.^{[citation needed]}

Before the advent of Old Dutch or any of the Germanic languages, Germanic dialects were mutually intelligible. The North Sea Germanic languages were spoken in the whole of the coastal parts of the Netherlands and Belgium. Old Frisian was one of these languages, and elements of it survived through the Frisian language, spoken in the province of Friesland in the North of the Netherlands. In the rest of the coastal region, these languages were mostly displaced following the withdrawal to England of the migrating Angles, Saxons and Jutes, who gave rise to Old English.

It was largely replaced by Weser–Rhine Germanic dialects, spoken by the Salian Franks. It spread from northern Belgium and the southern Netherlands to the coast and evolved into Old Dutch. It has, however, a North sea Germanic substrate. Linguists typically date this transition to around the 5th century.
